Bass trap in a difficult corner


I have a corner that has very little space for a bass trap. On that wall is a large book end which I think makes for a decent diffuser but there is still a corner right next to the bookshelf that is completely exposed. On the adjacent corner is a trap. Will that be enough?

Thanks. I've seen the GIK website and the price seems right. That pillar traps looks interesting, too.
I have a corner in my room that I cannot block because it is the access to my system. I am making a DIY 20" round trap on wheels so I can move it when I have to easily.
Believe it or not, those tubes they roll rugs on make great bass traps when installed in corners, and they are free. Just go anywhere rugs are sold and ask for them.
Don't forget the corners where your walls meet the ceiling (all the way across the wall, not just in the upper corners). If you don't have room in a standard corner, put your traps up high. The GIK traps work very nice.
